Hi, > Finally, Jens are able to figure out what MeijerG[{{1, 1}, {1/2}}, > {{1, 1}, {0, 0, 0}}, r, 1/2] in terms of elementary functions is for > the links that you posted? > You asked for "So how can I find out what MeijerG[{{1, 1}, {1/2}}, {{1, 1}, {0, 0, 0}}, r, 1/2]? really is" This can mean almost every thing, is it a philosophical question? And the answer would be "It is nothing real, it is pure fiction." The only way to simplify MeijerG[] would involve the usage of the relations you can find in the pages I have posted. And Mathematica will probably not apply all the transformations listed in the pages. Especial if you wish to get a special form of the output, Mathematica will not able to find it. It is always hard to force Mathematica to bring the result in a special form, but it is impossible if we don't know what you want. Regards Jens
